摘要：
A method for measuring the mobility of a lubricant located on the top surface of a disk used in hard disk drives. The method includes forming one or more scribe lines in a lubricant layer of the disk. The disk is then spun by a spin stand where lubricant moves in response to the centrifugal forces of the spinning disk. The disk is removed from the spin stand and the height of lubricant that moved into the scribe line is measured to determine lubricant mobility.
